6. Convert Item Description to Clean HTML
Usually, descriptions are copy-pasted from a website or Word/PDF file and they contain a lot of embedded styles. This messes up the Print view of your invoices or quotes.
To fix this, you can check "Convert Item Description to Clean HTML" in Stock Settings. This will ensure that when you save the Items, their descriptions will be cleaned up.
If you want to control your description, views, and allow any HTML to be embedded, you can uncheck this property.
7. Auto insert
7.1 Auto insert Price List rate if missing
Enabling this will insert an Item Price to the Price List of an Item automatically when using the Item in its first transaction. This price is fetched from the 'Rate' set in the first transaction with the Item. The Price List depends on whether you're using a Purchase or Sales transaction.
Note that, the Item Price will be automatically inserted only in the first transaction if not already present.
If this is unticked, the 'Standard Selling Rate' set in the Item when creating the Item will be added as Item Price.
7.2 Automatically Set Serial Nos based on FIFO
Serial numbers for stock will be set automatically based on the Items entered based on first in first out. The Serial Numbers will be set automatically in transactions like Purchase/Sales Invoices, Delivery Notes, etc.
8. Allow Negative Stock
This will allow stock items to be displayed in negative values. Using this option depends on your use case. For example, the stock transaction entries are entered at the weekend or month-end. In this case, negative stock needs to be enabled so that you can continue with your purchase/sales transaction entries.
9. Set Qty in Transactions based on Serial No Input
The quantity of items will be set according to the serial numbers. For example, if the user has added serial nos like A001, A002, and A003 then the system will set the quantity as 3 in the transaction.
